LONGEST SLEEPING ANIMALS
Bears
The largest hibernators are the bears, but they aren’t true hibernators because they go into torpor during winter only if they live in cold areas.
They can wake up and move around periodically
What make bears unique is that during hibernation they do not eat and drink all, and excrete rarely, for more than three months to sometimes as long as six months!
Hibernating black bears, particularly mothers with cubs, sleep lightly, they can wake if disturbed, though some may take a while to do so.
In January, a female black bear may give birth in the den to one or more cubs. She then goes back to sleep, waking up every now and then to tend to the cubs. The cubs, meanwhile, do not hibernate but stay curled up by their mother. By spring, the mum and cubs, which are now about three months old and weigh four to eight pounds, leave the den
